Fluoride in Selmer’s water: not fluoridated — and it hasn’t been since about 2011
Selmer fluoridated its water for nearly four decades, then the arrangement that supplied the fluoride fell apart around 2010–11 and was never replaced. Here is exactly what we verified, what it means for your teeth, and how to check it yourself.
No — Selmer’s city water is not fluoridated today. The Selmer Water System (TN0000615) added fluoride from 1973 until about 2010–11, when its supply arrangement ended; it has not added fluoride since. Its 2024 and 2025 water quality reports list no fluoride at all — so there is no current Selmer fluoride level to report, and this page won’t invent one.
How to read this page: Selmer is a “no level” page. Where a fact is verified, we say so and cite it. Where the record runs out — including the absence of any formal repeal vote — we say that too, in plain sight, instead of filling the gap with a guess.

Selmer fluoride, at a glance
- Water system
- Selmer Water System — the public water system serving Selmer, Tennessee
- System ID (PWSID)
- TN0000615
- Fluoridation status
- Not fluoridated — fluoride was added from 1973 until about 2010–11 and has not been added since
- Current fluoride level
- None — not fluoridated. There is no current mg/L figure for Selmer, because no fluoride is being added. The utility’s 2024 and 2025 Consumer Confidence Reports contain no fluoride row at all.
- Nearby systems
- Eastview Utility District purchases its water from Selmer, so it follows Selmer’s not-fluoridated status. Michie Water Department is independent — Selmer’s status doesn’t settle Michie’s, so check with Michie directly.
How Selmer stopped fluoridating: a supplier story, not a vote
Selmer’s fluoridation didn’t end with a headline or a referendum. It ended with paperwork, a departing supplier, and an empty bid process — so we’re careful below about exactly what the record does and doesn’t show.
Selmer began fluoridating its water in 1973 and continued for roughly 37 years. Around 2010–11, accountability criteria in the city’s Ordinance #592 led the system’s fluoride supplier to remove its equipment and products from the water system. The city then sought bids to set up a replacement supply arrangement — and the bids drew no responses. With no supplier and no replacement, fluoridation simply never resumed.
One thing the record does not contain: we found no record of a formal vote to repeal fluoridation. So this page doesn’t claim one happened. What ended fluoridation in Selmer was the collapse of a supply arrangement, not a council decision anyone can point to — and the result, a decade and a half later, is the same either way: no fluoride is added to Selmer’s water today.
What backs up the “not fluoridated” finding
- The Selmer Water System’s 2024 Consumer Confidence Report contains no fluoride row at all.
- Its 2025 Consumer Confidence Report likewise contains no fluoride row — read it yourself in How to confirm.
- EWG Tap Water Database data for 2021–2023 shows no fluoride detection for the system.
The benchmarks — and why Selmer has no number next to them
Three numbers frame every fluoride conversation, and people constantly mix them up. Here they are, kept separate — with Selmer’s row marked honestly: there is no Selmer level, because Selmer does not fluoridate.
| Level | Value | What it means |
|---|---|---|
| Selmer Water System — current level | Not fluoridated — no level | Selmer does not add fluoride, so there is no current fluoride level in mg/L to publish. Any mg/L figure presented as “Selmer’s level” would be invented. |
| CDC recommended level | 0.7 mg/L | The U.S. Public Health Service / CDC target for systems that do fluoridate — the level meant to prevent cavities while minimizing cosmetic fluorosis. Selmer is not targeting it, because Selmer is not fluoridating. |
| EPA secondary standard (SMCL) | 2.0 mg/L | A non-enforceable guideline set to protect children against tooth discoloration (cosmetic fluorosis). Systems above it must notify the public. |
| EPA enforceable maximum (MCL) | 4.0 mg/L | The legal ceiling. Above this, a system is in violation — the standard is set to protect against bone and severe tooth damage. |
Read the table carefully: the three benchmark numbers describe the rules for fluoride in drinking water generally. None of them is Selmer’s level. Selmer’s entry is the first row — not fluoridated, no level.
What this means for your teeth
Not-fluoridated water isn’t good news or bad news on this page — it’s a fact with practical consequences. The main one: the fluoride your teeth get has to come from somewhere, and in Selmer that somewhere is your bathroom sink and your dentist’s office, not your tap.
01 Toothpaste matters more, not less
Fluoride toothpaste is the main event for your teeth regardless of what’s in the water — it delivers fluoride directly to the enamel, twice a day. In a fluoridated town, the water is a quiet background layer underneath that habit. In Selmer, there is no background layer, so the toothpaste habit carries more weight, not less. Skipping it costs you more here than it would somewhere the water is fluoridated.
02 Kids’ amounts, per the ADA
For children, the amount on the brush matters: a rice-grain smear of fluoride toothpaste for children under age 3, and a pea-size amount for ages 3 and up. Teach kids to spit, not swallow, and supervise brushing until they can manage it reliably. In a non-fluoridated town, fluoride toothpaste is doing the work the water isn’t — but more toothpaste than the ADA amounts is not better.
03 Consistency is the whole game
Water fluoridation quietly covered a lot of missed brushings and sugary days. Without it, protection rises and falls with your actual routine: twice-daily brushing, cleaning between teeth, and how often sugar and acidic drinks hit your teeth during the day. Nothing exotic — just fewer free passes.
04 Supplements: professional advice only
Fluoride supplements exist for children in non-fluoridated areas, and Selmer is one — but the right call depends on your child’s total fluoride exposure from toothpaste, diet, and any other sources. Don’t start supplements on your own. Ask a dentist or pediatrician to weigh the whole picture first.

In-office fluoride varnish: worth more in a town like Selmer
Varnish is a concentrated fluoride coating a dental office paints onto your teeth in a couple of minutes, usually at a regular checkup. It’s a modest intervention everywhere — but in a non-fluoridated town, it’s filling a gap that fluoridated water fills elsewhere, so it’s worth more here than in a fluoridated city.
Who tends to benefit most:
01 Kids — especially with a cavity history
Children get the clearest benefit, and children who have already had cavities get the most. If your child has had a filling, varnish at checkups is one of the simplest ways to lower the odds of the next one.
02 Adults at higher risk
Adults with dry mouth (a common medication side effect), a pattern of frequent cavities, exposed root surfaces, or braces have more at stake. For a low-risk adult with no cavity history, varnish is a smaller deal — worth discussing, not worth overselling.
The honest framing: varnish is one layer, applied a few times a year. It does not replace fluoride toothpaste, and it doesn’t make anyone cavity-proof. But where the water contributes nothing, each of the remaining layers matters more — and varnish is the easiest one to add. Ask about it at your next checkup, and ask what it costs before it’s applied.
The fluoride-free question, stated fairly
Some Selmer residents prefer their water without added fluoride — as a matter of personal choice about what goes into their tap water, or out of caution about fluoride itself. That preference is a legitimate position, and this page isn’t here to argue anyone out of it. It is here to state the trade-off plainly.
Here is what the evidence generally shows when a community stops fluoridating: cavity rates tend to creep up, with the clearest effects in children — the group with the least control over its own brushing, diet, and dental visits. The effect is real but not dramatic, because fluoride toothpaste is now widespread in a way it wasn’t when fluoridation began; toothpaste blunts much of the difference. Neither extreme claim holds up: unfluoridated water is not a dental catastrophe, and removing fluoride is not cost-free for teeth either. It is a trade-off between a population-level benefit and a household-level choice.
Selmer’s situation has one extra wrinkle: the change here wasn’t the product of a public debate and decision — it followed a supplier’s departure and an empty bid process. Whatever your view of fluoridation, the practical response for a Selmer household is the same: know that the water contributes no fluoride, and make sure toothpaste and checkups are doing that work instead.
On a private well? None of this is automatic
Private wells are unregulated — test first
Plenty of McNairy County homes outside the city system drink from private wells. Nobody adds fluoride to a well, and no agency monitors one the way public systems are monitored. Well water can carry naturally occurring fluoride at low levels — or, occasionally, levels high enough to matter for young kids’ developing teeth.
So the order of operations is: test first, then decide. Get your well water tested for fluoride, take the result to your dentist, and only then decide whether your household needs more fluoride (toothpaste, varnish) or less. Guessing in either direction is how kids end up under- or over-exposed.
How to confirm Selmer’s status yourself
You don’t have to take this page’s word for it. The proof is in the utility’s own reports — and in this case, the proof is an absence: the fluoride row that simply isn’t there.
- Check the name on your water bill first. If it says Eastview Utility District, this page’s answer is still yours — Eastview buys its water from Selmer and follows Selmer’s not-fluoridated status. If it says Michie Water Department, your system is independent of Selmer; ask Michie directly.
- Read the Selmer Water System’s 2025 Consumer Confidence Report. Here it is: Selmer 2025 CCR (PDF). Look at the detected-contaminants tables and note what’s missing: there is no fluoride row at all — the same as in the 2024 report. A system that adds fluoride reports fluoride; Selmer’s report doesn’t, because Selmer doesn’t add it.
- Cross-check with the CDC’s My Water’s Fluoride. The CDC’s lookup at nccd.cdc.gov/DOH_MWF collects state-reported fluoridation data by system. States report voluntarily and it isn’t real-time — if it ever disagrees with the utility’s current CCR, trust the CCR.
- Still unsure? Ask the utility the direct question: “Do you currently add fluoride to the water?” For Selmer, the answer today is no — and it has been no since about 2010–11.
Questions people actually ask
Asked the way people actually ask them — answered only from what we could verify.
No — not today. The Selmer Water System (TN0000615) added fluoride from 1973 until about 2010–11, but it does not add fluoride now. The utility’s 2024 and 2025 Consumer Confidence Reports contain no fluoride row at all, and EWG Tap Water Database data for 2021–2023 shows no fluoride detection. There is no current fluoride level to report for Selmer, because there is no fluoride being added.
The supply arrangement ended, not a vote we can point to. Around 2010–11, accountability criteria in the city’s Ordinance #592 led Selmer’s fluoride supplier to remove its equipment and products from the system. The city sought bids to set up a replacement arrangement and received no bids, and fluoridation never resumed. We found no record of a formal vote to repeal fluoridation — what ended it was the supplier leaving and no replacement stepping in.
There isn’t one to publish — Selmer’s water is not fluoridated, so there is no current mg/L figure for Selmer, and we won’t invent one. For context only, the national reference points are: the CDC recommends 0.7 mg/L for fluoridated systems, the EPA’s secondary standard is 2.0 mg/L, and the EPA’s enforceable maximum is 4.0 mg/L. Those are benchmarks other systems are measured against — they are not Selmer’s level.
It depends on your system. Eastview Utility District purchases its water from Selmer, so Eastview follows Selmer’s not-fluoridated status. Michie Water Department is independent — Selmer’s status doesn’t decide Michie’s, so check with Michie directly. The reliable test is the system name on your water bill: if it isn’t the Selmer Water System or Eastview, ask your own system.
Lean on the layer you control: brush twice a day with fluoride toothpaste — a rice-grain smear for children under 3 and a pea-size amount for ages 3 and up, per the ADA. Without fluoridated water, in-office fluoride varnish is worth more, especially for kids and higher-risk adults, so ask about it at checkups. Take fluoride supplements only on a dentist’s or pediatrician’s advice — the right call depends on your child’s total fluoride exposure.
No — nobody adds fluoride to a private well, and private wells aren’t regulated the way city systems are. Well water can carry naturally occurring fluoride at low or occasionally high levels. Test first, then decide with your dentist whether your household needs more fluoride or less.

Method in one line: Selmer’s not-fluoridated status is verified three ways — the absence of any fluoride row in the utility’s 2024 and 2025 Consumer Confidence Reports, and no fluoride detection in EWG data for 2021–2023. Because the system does not fluoridate, there is no current fluoride level for Selmer, and this page publishes none rather than estimate one. The history is stated as the record supports it: fluoridation ran 1973 to about 2010–11 and ended when the supply arrangement collapsed; no formal repeal vote was found, so none is claimed.
